Tomographic imaging techniques such as micro-computed tomography and magnetic resonance imaging (MRI) permit to gather digital anatomical data of whole specimens non-invasively. The resulting datasets can be used for direct observation of virtual tomographic sections as well as for manual and semi-automated three-dimensional modeling. Living, freshly fixed, as well as museum material can be analyzed successfully using this approach, giving the zoologist a powerful set of tools for large-scale comparative anatomical studies, both qualitatively and quantitatively. This presentation will focus on applications of non-invasive imaging techniques primarily for the study of marine invertebrate taxa such as echinoderms and mollusks. Furthermore, pathways for the communication of three-dimensional models in scientific publications, academic presentations, and to a broader audience through the internet will be highlighted.
